We've been having problems on our 892E LC lately. It won't boom up while travelling and arm and bucket seem weak. I hooked up a couple of gauges and this is what I have for pressures.
Pilot @ filter 1200 psi oil cold
SE pressure on Regulator 300 neutral
100 arm or bucket fully stroked also mode has no effect on pressure
Both pumps make over 5k psi on track circuits
Front pump pressure wont drop below 1000psi
I pulled SB spool and sleeve at solenoid valve 1 but didn't find anything
Why won't front pump pressure drop back to 0psi, and SE pressure should be close to pilot pressure shoudln't it. Where do I need to test from here?
